1 General
The LC-151 is a unique motion detector utilizing a single passive infra-red element and
Microwave technology for use outdoors in harsh environments.
The LC-151 is designed for outdoor use in the most severe and climatic conditions and may also
accommodate pets with the addition of optional pet immunity lenses.
High reliability is achieved by combining both dual tech hardware with highly sophisticated
software, greatly reducing the possibility of false alarms.
The active elements are comprised of a single element PIR and advanced Microwave detector
inside a stylish, rigid plastic body.
These special optics combined with a Microwave Doppler sensor assures elimination of “false
alarms” while maintaining high security standards for the detection of human intruders into the
protected area.
The detection sensitivity and range is controlled by a potentiometer allowing fine tuning, so that
the correct detection pattern will be set for every installation.
The LC-151 is designed to protect large areas and can easily be installed on walls in order to
provide a solid protection of the area while rejects interferences from birds and small animals due
to the optional “PET MASK” optics.

3 Assembly description
The LC-151 is a robust yet small detector which includes a large LED indicator that can be easily
observed from long distances to provide indication of intrusion. Using the supplied mounting
bracket, the LC-151 can be easily mounted to walls using the provided mounting screws. For
installations requiring the detection beam to be adjusted horizontally or vertically to obtain the
desired field of protection use the LC-B1-15X Outdoor Mounting Bracket pictured below. (not
included)
